Good call. However, on checking it looks like Alpha have actually released both versions. As far as I can tell, the 1936 UK remake isn't in the public domain but as usual such trivialities don't stop Alpha. Both their DVDs are vanilla and to differentiate them on this site they'd need the timings, an Amazon link and a note adding. The ASINs for the UK remake are B004PYHHI0 (Renown) and B0025X4PE2 (Alpha).
I'm surprised there's no entry yet for D.W. Griffith's silent classic. As no BD is forthcoming, it's time I picked up Kino's disc. Of course, me finally buying it will guarantee an immediate BD release!
